Yeah, I had to rub my eyeballs when I saw this report on TorrentFreak, too. Evidently a Finnish group set up an antipiracy site (above) by ripping off The Pirate Bay's symbols and site code. TPB took the bait, threatening to sue if the site didn't stop using its symbols.

The Pirate Bay is the flagship site for those who consider the piracy of movies, video games, music and whatever to be both a political movement and a lifestyle. It's based out of Sweden, its founders have been taken to trial, and some countries block access to its IPs by law. CIAPC is the Finnish group baiting The Pirate Bay, essentially spoofing that site but replacing torrent and search links with links to antipiracy messages. TorrentFreak said The Pirate Bay, in a message on their site, threatened CIAPC with a lawsuit if it didn't take the site down.

Though it has yet to be sued, CIAPC itself encourages The Pirate Bay to take them to court, and not just for the humor value of a bunch of pirates suing someone for copyright infringement. An action against CIAPC would expose those Pirate Bay leaders who operate in anonymity, probably a big reason why TPB has yet to go through with this. So far there's been a garden-variety DDoS attack on CIAPC, undoubtedly carried out by sympathizers, and TorrentFreak says The Pirate Bay is examining its legal options with the help of a third party, probably so its leaders can remain in the shadows.
